Patented Oct. 11, 1932 UNITED STATES PATENT OFFICE ERNESTO HOYOS,BOSTON, MASSACHUSETTS, ASSIGNOR TO HUDSON MOTOR CAR ..COMP.ANY, OFDETROIT, MICHIGFN, A CORPORATION OF MIGHIGAN s'rnrrine DEVICE ron ATOMOBILE. BODIES Application filed April 11, 1928. Serial No. 269,122.

This invention relates to striping devices particularly adapted for thepurpose of applying different colored stripes to automobile bodies, suchas along or adjacent the belt line' molding or around the windowreveals.

An object of the invention is to provide a striping device which may beused by unskilled workmen to apply one or a plurality of stripes to thebody rapidly and in an efli-- cient manner, and in which different widthstripes may be applied by the same device or in which any number ofstripes different distances apart may be applied at the same time.

Another object of the invention is to provide a-striping device whichmay be moved over the body panel more easily and rapidly while enablinga better and more clearly de fined stripe to be produced withoutrequiring 0 any particular skill to'produce this result. One of thefeatures of the present invention resides in the factthat the feed ofpaint or striping fluid to the applicator may be automatieally increasedor decreased by centrifugal action during operation in proportion to thespeed of movement of the device.

Other objects of this invention will appear in the following descriptionand appended claims, reference being bad to the accompanying drawingforming a part of this specification wherein like reference charactersdesignate corresponding parts in the several views.

Fig. 7 is a detail sectional view illustrating different types ofapplicators which may be interchangeably use Referring to the drawingswherein I have shown for the purpose of illustration a striplng deviceembodying my invention, the device may comprise a suitable support 9provided with a suitable reservoir 10 for containing the paint or otherstriping fluid. This reservoir has a detachable cover 11, and the deviceis provided with a handle or hand grip 12. The support has a downwardlyextending arm 13 provided with a passage or duct 14: communicating withthe interior of the reservoir 10 and providing a gravity feed. The freeend of the supporting arm 13 is turned down at 13a and threaded toprovide a means whereby different types of appllcators may beinterchangeably connected to the supporting arm 13.

In the construction shown in Figs. 1 and 2 the striping instrumentalitycomprises a rotary disk. Where a single stripe is to be made on the bodypanel, a single striping disk will be employed, and the construction issuch that disks of different sizes may be interchangeably used dependingupon the width of stripe desired or a plurality of striping disks may beconnected to the sup- 1 port 13 where a plurality of parallel stripesare to be made. In Figs. 1 and 2 I have shown by way of example threedisks assembled in position on the supporting arm 13, as a result ofwhich three parallel stripes may be simultaneously made. The stripingdisk in the present instance is rotatably mounted on the end of the arm13 through the medium of a ball bearing comprising a collar 15 screwedonto the threaded end 13a of the arm and a pair of revoluble members 16and 17 having cooperating threaded portions, and between which and thecollar 1 extension similar to the threaded portion 13a to which may beattached any one of the disks 18 illustrated in Figs. 1 and 2, or themodified type of disk 35 illustrated in Figs. 5 and 6. Each of thestriping disks 18 comprises a central hub 19 having at one end. a tappedbore adapted to be screwed onto the threaded extension 17a of thebearing member 17 and having at the opposite end a threaded portion 20to which may be attached another striping disk 18 in the manner shown inFig. 2. From this construction it will be seen that each disk 18 may beinterchangeably connected to the end of the bearing member 17 and to anyone of-the other disks so that if desired a plurality of striping disksmay be assembled together and to the end of the supporting arm 13.

A cap 22 having a tapped bore may be screwed on to the threaded end 20of any one of the hubs 19, and this cap is conical to provide, as in theconstruction shown in Fig. 2, a bearing member capable of being seatedin a conical recess in an adjustable bearing member 23. The latterterminates in a sleeve portion 23a drilled to receive a supporting rod24. This rod is adjustable within acylindrical hole 25 in a tubularextension 26 of the body. The rod has a longitudinal keyway 27 and maybe clamped in adjusted position by means of a set screw 27a extendinginto the keyway to hold the supporting rod 24 against turning.

In like manner the sleeve portion 23a of the bearing 23 may be clampedin adiusted position on the rod 24 by means of a set screw 28 proiectinginto the keywav 27 to hold the bearing against turning on the rod Thebearing members 15. 16 and 17 have an axial bore registering with theduct 14 and the fluid is conducted from the duct 14 into the axial bore29 of the striping disk 18 by means of a tube 30 extending through thebearing 15-17. The uner end of this tube has a laterally extendingannular flange which is clamped between the end of the arm 13 and theshoulder of the tapped counterbore of the member 15 as shown in Fig. 2.It will be seen that a continuous passage is provided from the chamber10 to the axis of rotation of each striping disk 18 by means of the duct14, tube 30 and duct 29. Each disk may comprise a hollow annular bodyfixed on the hub 19 through which extend radial ports 31 into thechamber 32 of the hollow disk body. The periphery of the disk 18 isprovided with an annular applicator pad 33 which may be composed offelt, sponge, or other porous material providing a yielding pad. Thefluid may pass from the hollow body 32 into the pad by means of a seriesof ports 34.

In Figs. 5 and 6 I have shown a. somewhat modified type of rotarystriping disk. This disk 35 also comprises a central hub 35a havingspaced radially projecting flanges 36 suitably spaced at the peripherythereof to enable a stripe of the'desired width to be applied. Theflanges 36 are held'under tension in adjusted position by means of caps37 screwed onto the opposite ends of the central hub member 35. stripingdisk 18, the hub of the disk 35 is constructed so that it may beattached to the end of the bearing member 17 by means of a tapped bore38. This hub is also provided with a threaded extension 39 to which-maybe attached another striping disk or the hearing cap 22. The hub isdrilled centrally to provide an axial fluid passage 40 and fluid isconducted to the flanged nibs 36 by means of radial tubes or ducts 41.

In Fig. 7 I have illustrated the manner in As in the case of the Y whichtwo other types of applicators 42 and 47 may be interchangeably employedif required. The applicator 42 is shown as a pen having a base 43 whichis drilled to provide a fluid passage 44 communicating with the passage14 of the support 13. This base 43 of the pen has a tapped eounterboreadapted to be screwed on to the threaded extension 1311 and also has athreaded extension 43?; to which may be attached either another stripingpen as shown in Fig. 7, or a spacer member 45, or the bearing cap 22. InFig. 7, I have illustrated a spacer member 45 interposed'between thebase 43 of the pen 42 and the base 46 of a striping brush 47, this typeof applicator being shown for illustrative purposes. The base 46 is alsoprovided with a fluid passage 48 alined with the passage 49 extendingthrough the spacer 45, the passage 49 being alined with the passage 44.The cap 22 is screwed onto the threaded end of the member 46 closing theend of the fluid passage.

The paint or fluid is conducted from the duct 44 to the pen 42 by meansof a tube 75, and is conducted from the duct 48 into the brush 47 bymeans of a tube 76.

Referring to Fig. 4, it will be noted that the spacer 45 is drilledaxially to provide a duct 49. One end is counterbored and tapped at 450to permit the spacer to be screwed onto any of the threaded portions13a, and 20 or to be attached to either of the parts 43 and 46 of theapplicators 42 and 47. The opposite end of the spacer 45 is turned downand threaded at 45?). So that from the construction it will beunderstood that the proper positioning of the applicators with referenceto the support 9, or the desired spacing of the stripes where more thanone stripe is being made may be-obtained merely by proper interchangingof the parts.

As illustrated in Figs. 1 and 2, the striping device is provided with aguide which may be adjusted into various positions in order to determinethe position of the stripe on the body. When making a stripe along oradjacent the belt line molding M the guide 50 travels along this moldingand by ad-.

' the action of a spring 55 and this movement is limited by means of asuitable pin and slot connection 56. In this manner, it will be seenthat the guide 50 is mounted to yield by virtue of the spring 55, andmay be adjusted longitudinally within the head 52 or it may be adjustedbodily by adjusting the rod 24 within the bore 25 of the tube 26.

The flow of fluid from the reservoir 10 through the duct 14 iscontrolled by means of a valve 60. This valve in the present instance isof the rotary type which may be rotated into one position to close thepassage or into position to open the passage and this operation isaccomplished by means of a trigger device 61 located adjacent the handgrip 12 so that it may be operated by the index finger of the workman.The trigger 61 is controlled by a spring 61a and is secured to a spindle62 to which is pinned a link 63. The link 63 has a lost motionconnection, by means of apin and slot 64, to a link 65 pinned to thespindle of the valve 60. When the trigger 61 is in the full-lineposition shown in Fig. 3, the valve will be closed as shown in Fig. 2.When operating thestriping device to form a stripe on the body, thetrigger 61 is retracted to the dotted line position shown in Fig. 3,thereby operating the mechanism as shown in dotted lines in the figurepesulting in turning the valve into open posi- It will be seen that thepaint or other striping fluid is normally fed from the reservoir 10through the conduit 14 to the axis of the striping disks by gravity. Asthe device is moved along the body panel, it will be understood that thedisks are rotated more or less rapidly as a result of which the fluidwill be spread evenly to the periphery of the disk by centrifugalaction.

It is important that a proper supply of I paint be fed to the peripheryof the disks and this supply should increase in proportion to the speedin which the device is moved over-the body. When the device is movedslowly over the body panel a suificient supply of fluid will be obtainedby the gravity feed, and due to the rotation of the disks the paint willspread from the axis of rotation to the periphery in an even and uniformmanner. As the movement of the device is increased however, the feed isincreasingly assisted by centrifugal action set up by the rapid rotationof the disks. Hence it will be seen that by virtue of this constructionthe supply of fluid will be increased or decreased at the periphery ofthe striping disk in proportion to the speed of travel of the deviceover the body.

What I claim is:

1. In a striping device, the combination of a support, a reservoir, aplurality of striping applicators, said supporthaving a conduitcommunicating with the reservoir and having means for attachment to eachof said applicators, and said applicators having means forinterchangeably attaching one to the other.
